Some el.components are loose on tv circuit board.I have removed the back cover,supported tv picture tube 45 deg.against wall.This tv is heavy!One screw on left holds the circuit board to bottom case.Removed and supported this board on few heavy books.Turned tv on and gently probed all the componets on top of the board with plastic drinking straw.In my case transistors Q-830 and Q-421 needed resolder loose joints.These components are mounted on flat aluminium heat sink strips located sligtly left of center of the circuit board.Also blobed bit of silicone into base hole and foot of alu.heat sink to support it.
your television is going to need an internal repair. most likely in the power supply of the television. it would be best to unplug the television until it can be repaired.

If you mean thin white lines, this is is an indication of a problem in the Horizontal Drive ckt. most likely the Damper Diode has opened or shorted, this would cause the visual symptom and then the set would shut down, unfortunately this is a problem best left to a qualified technician to repair, hope this helps.
